5842  * When a userspace application wants to play a video, the content follows a
5843  * standard format definition that usually specifies the FPS for that format.
5844  * The below list illustrates some video format and the expected FPS,
5845  * respectively:
5846  *
5847  * - TV/NTSC (23.976 FPS)
5848  * - Cinema (24 FPS)
5849  * - TV/PAL (25 FPS)
5850  * - TV/NTSC (29.97 FPS)
5851  * - TV/NTSC (30 FPS)
5852  * - Cinema HFR (48 FPS)
5853  * - TV/PAL (50 FPS)
5854  * - Commonly used (60 FPS)
5855  * - Multiples of 24 (48,72,96 FPS)
5856  *
5857  * The list of standards video format is not huge and can be added to the
5858  * connector modeset list beforehand. With that, userspace can leverage
5859  * FreeSync to extends the front porch in order to attain the target refresh
5860  * rate. Such a switch will happen seamlessly, without screen blanking or
5861  * reprogramming of the output in any other way. If the userspace requests a
5862  * modesetting change compatible with FreeSync modes that only differ in the
5863  * refresh rate, DC will skip the full update and avoid blink during the
5864  * transition. For example, the video player can change the modesetting from
5865  * 60Hz to 30Hz for playing TV/NTSC content when it goes full screen without
5866  * causing any display blink. This same concept can be applied to a mode
5867  * setting change.
